If the RAID controller bites the bullet you are usually toast unless you
have another RAID controller (same manufacturer and type) as a spare.
None of these controllers are self contained raids, it is all by mdadm
and friends.
mdadm, zfs and btrfs all lack this problem.
I have zero luck replacing one companies raid controller with another and
ditto on raid built into the motherboard.
As above.
I really don't need any help losing my data/files as I do a good job of that
all by myself ;)
btrfs and zfs have snapshots which really help avoiding losing
data. On other machines, rsnapshot is often suitable.
I found it is better to just have my data on several backup disks, that way
if one fails I get another disk and copy all the data to the newly purchased
disk.
RAID isn't a backup solution, it's a way of keeping things going
until you have time to restore. (And also a way of improving
performance and/or manageability.)
If you don't need or want it, you shouldn't use it. Same as any
tool.
